Autism is a complex neurobehavioral disorder that includes impairments in social interaction and developmental language and communication skills combined with rigid, repetitive behaviors. The disorder covers a large spectrum of symptoms, skills, and levels of impairment. It ranges in severity from a handicap that somewhat limits an otherwise normal life to a devastating disability that may require institutional care.
Children with autism have trouble communicating. They have trouble understanding...
One in 150 children is now affected with ASD, according to the CDC. Because ASD is on a spectrum, many children are mildly affected, with less severe symptoms. So the behaviors that typically point to ''classic" autism may not be as pronounced or may be absent, says Paul Shattuck, PhD, an autism researcher at Washington University in St. Louis.
Further complicating things, autism is often accompanied by other problems, such as gastrointestinal ailments, hearing impairment, or behavior problems. "Autism often comes with something else," Shattuck says.
The age at which ASD is diagnosed can vary greatly, says Shattuck. In some children, he says, the disorder is apparent at 18 months. "You just know," he says. With other children, the autism diagnosis may not be confirmed until age 5 or so.
Parents can educate themselves about the typical symptoms, realizing that not every child has all the same symptoms or the same severity of symptoms. In general, children with ASD are socially impaired, may have language or communication difficulties, and exhibit some unusual behaviors, such as avoiding eye contact, resisting changes in routine, or declining to cuddle or have other human contact.
Parents who pay careful attention and who know what to look for can become aware of certain "red flags" that demand immediate professional attention, even if they don't turn out to be ASD symptoms, according to the American Academy of Pediatrics. Among them: the child arches his back instead of snuggling when picked up; doesn't make much eye contact, or loses language or social skills at any age.
Pay attention, too, to everyday interactions, Shattuck says. A toddler who never wants to be held, for instance, is a warning sign and something to talk to your pediatrician about as soon as possible. If language skills seem to be lagging, that's a concern. A 15-month-old, for instance, should be able to say single words; a 24-month-old should be able to say two-word phrases.
